Saint Laurent’s Sac de Jour has quietly-yet-deliberately infiltrated the hearts and minds of celebrities over the past year. It’s not that the bag itself is remarkable; it’s really not, which may be part of the appeal. It’s sort of an anti-“it” bag–classically styled and fairly inconspicuous, with minimal branding. Our readers have always been quick to point out the similarities between the Sac and several other high end handbags (the Birkin, the Prada Saffiano Lux Tote), and they’re not wrong. So what is it about the Sac? Is it possible Saint Laurent is handing these out to celebrities like they’re soft pretzel samples from Auntie Anne’s, or are celebs going out and buying them en masse? We’ll investigate that, plus the rest of the week’s notable celebrity picks, below.

Kerry Washington
Christian Louboutin mini sweet Charity Bag
$1,595 via Net-a-Porter
First, we’ll start with the non-Sac-carrying celebs. Here’s Kerry Washington, heading into an appearance on Jimmy Kimmel live in LA with an adorable mini from Christian Louboutin. The sweet Charity is one of only a few bags that have lasted the long haul with Louboutin. As I’ve mentioned a few times in recent round-ups, it seems that the majority of their bag designs are being phased out in favor of new models to come.

Jenna Dewan-Tatum
Rauwolf Gemstone Clutch
$1,190 via Barneys
Jenna Dewan-Tatum is swiftly becoming one of our round-up regulars. here she is walking the red carpet at the premiere of Channing’s new sci-fi flick, Jupiter Ascending, carrying a shimmery brown clutch from Rauwolf. Rauwolf is a NY-based accessories brand that specializes in handcrafted clutches that vend for around $1-2K.

Alyson Hannigan
Balenciaga Papier Envelope Crossbody Bag
$1,245 via Bergdorf Goodman
Alyson Hannigan recently grabbed some lunch at the Brentwood country Mart in LA with her husband Alexis Denisof and a Balenciaga bag which I’m particularly fond of. There aren’t a lot of Balenciaga bags I’m not particularly fond of, to be honest, but this one is more discreet than most.

Kate Beckinsale
Saint Laurent Sac de Jour Bag
$2,890 via MATCHESFASHION.COM
Now begins the parade of Saint Laurent Sac de Jours. Kate Beckinsale was recently spotted at LAX with a classic black Sac with a textured front panel. This is technically the “small” (but not mini) Sac de Jour, as opposed to the notably larger, regular tote version.

Nicole Richie
Chanel vintage Backpack
Nicole Richie was also snapped darting to her automobile outside LAX. If you’re a celeb and you’re trying to slip through the crowds at LAX unnoticed, here’s a tip: leave the Chanel backpack at home. You might as well shoot off a flare gun.

Padma Lakshmi
Chanel fringe classic Flap Bag
Padma Lakshmi was recently spotted throwing paparazzi some shade while hanging out with her daughter Krishna in NYC. She’s carrying an unusual fringed Chanel Flap Bag that comes in a luscious brown leather hue that we don’t see celebs favor too often.

Rosie Huntington-Whiteley
Saint Laurent Sac de Jour Tote
$3,490 via Net-a-Porter
If there is one person who could be solely responsible for the Sac’s popularity, it is undoubtedly Rosie. She has been known to carry other brands, but in the last year or so, she has amassed quite a collection of Sacs. here she is at LAX, with a simple black Sac, one of at least a half dozen she seems to own.

Salma Hayek
Saint Laurent Crocodile Sac de Jour Bag

Here’s Salma Hayek, trying to find her seat at a soccer game between Paris Saint Germain and Rennes in Paris. It’s no mystery why Salma carries one of the most luxe Sacs available–her husband runs the company that owns Saint Laurent. I would be extremely hesitant to carry this bag to a soccer game, however.
